What is MiEMi™?

During a normal show day you probably test everything at least once, some things more than once! You’ll test connections between units be it analog or digital signal flows, loudspeaker functionality, network connections, RF coverage and frequency management and lots more probably. How often do you check that the IEM’s are working correctly? It’s simple enough with generic fit, but how about custom fit? Thats a little more difficult isn’t it? Custom fit IEM’s are made for one person and one person only that makes it trickier to test them. What if there was a way to check them? What if you could measure a frequency trace and refer back to it?

Perhaps your an IEM dealer that needs a way to check if a set of IEM’s are damaged before sending them to repair?

Or an Audiophile that just wants to compare different sets of IEMs?

Now you can and thats where MiEMi™ comes in.

MiEMi™ (pronounced Mimi), is a small 35mm high by 25mm wide adapter that sits on the end of a standard size measurement mic and allows you to measure frequency traces of custom fit & generic in ear monitors. MiEMi™ is the tool that’s currently missing from your audio toolbox.

The idea behind MiEMi™ is to add a new level of functionality to the tools most audio people already own. MiEMi™ shares its DNA with lab standard occluded ear simulators and measures up pretty closely to them. It won’t cost you anywhere near as much so it won’t break your bank if you lose it or or drop it on tour, and its plastic parts are designed to be replicated by any 3D printer.

MiEMi is comprised of the following key components;

  1. Microphone adapter interchangeable and made to fit most standard size measurement mic’s
  2. EPDM Rubber O-ring, sits in the mic adapter
  3. 2 x Tuning spacers & 1 distance spacer, tunes MiEMi’s frequency response
  4. Inner container, holds the tuning spacer and connects MiEMi’s shell
  5. EPDM Rubber coupler, custom designed to fit and seal onto custom fit IEM’s. It’s what allows MiEMi to measure lows and snugly holds IEM’s while measuring.
  6. Top screw holds the rubber coupler and closes the body.

By using MiEMi™ to capture traces of your IEM’s at a point in time where they work perfectly you’ll have a trace you can compare to further down the line. If there’s a change you’ll be able to see it and identify any errors, If your artists all use the same model you’ll be able to compare between models and see how close the individual sets are. Sometimes it’s sufficient to have a trace of only the one side or type to compare others to sometimes you might want to take a trace of L & R of every single IEM.

MiEMi™ is designed to be used with the tools you carry anyway, a measurement mic, an RTA, so doesn’t require a huge reinvestment to make it work. It sits on the end of your measurement mic and interfaces your in ear monitors to your RTA.

Although MiEMi™ can give you a good idea of the frequency response of your IEM’s it’s designed to work with many different microphones. This means different mics will give slightly different responses, our experience with it is that the differences are from 4-5Khz up. What it can do is give you a very usable reference trace that you can use from day to day to see if everything is working correctly. It will also help you precisely set IEM’s with adjustable bass controls like some of JH Audios’s newer models.

Isn’t it about time you started checking your in ear monitors?
